Bonded steel plate bonding reinforcement is the use of structural glue to bond steel and reinforced members together, so that steel and reinforced members to achieve the purpose of strengthening the structure. In the process of reinforcement, some bonded steel glue and poured steel plate glue will be used. What are the similarities and differences between sticky steel glue and pouring steel glue when used? Now let me introduce HM to you.

In the code, sticky steel glue and poured steel glue are called coated sticky steel glue and poured sticky steel glue respectively. From their names, we can know that they still have many similarities. First of all, their parameters are the same except that the elastic modulus is different.

Of course, there are still many differences between viscose steel glue and poured steel glue, the easiest to distinguish is that viscose steel glue is paste, poured steel glue is liquid. Paste gum and liquid gum also have their own characteristics, I believe that the small partners engaged in testing reinforcement materials have also found. The elongation of viscose steel adhesive is the most difficult to reach the standard, and the elastic modulus of filling steel adhesive is the most difficult to qualify, so in the procurement of structural adhesive should pay special attention to the elongation of paste adhesive and the elastic modulus of liquid adhesive.

In the process of bonding steel, the thickness of the steel plate bonded by sticking steel glue should not be greater than 5mm, and the thickness of the steel plate bonded by pressure injection glue (filling steel glue) should not be greater than 10mm. This is mainly due to the pressure glue injection method can be poured into the steel plate through a certain pressure between the steel plate and the strengthened member, so that the steel plate and the strengthened member contact area more, can better ensure the reinforcement effect. Some of the positions where the steel plates are not compacted with glue can be treated by pressure glue injection. In addition, when the external bonding steel reinforcement method, the need to use steel glue.

In the process of reinforcement, not only the correct reinforcement process, but also to understand the characteristics of some materials to choose the correct reinforcement materials in order to achieve the reinforcement effect and ensure the structural safety. HM has been engaged in research and development, production and sales of reinforcement materials, with more than 150 national patents, a deeper understanding of reinforcement materials.
